Drawing a Center-Point Arc Line
In the modeler, a center-point arc line segment is an arced line defined by a center point, start point and angle. Use the Draw > Arc > Center Point function to create a polyline object with one or more center-point arc line segments.
- Click Draw > Arc > Center
Point.
- Select the center point of the arc in one of the following ways:
- Click the point.
- Type the point’s coordinates in the X, Y, and Z text boxes in the status bar.
- Select the start point, or radius, of the arc by clicking the point or typing the coordinates in the X, Y, and Z text boxes in the status bar.
- Sweep the angle, or endpoint, of the arc by clicking the point or typing the coordinates in the X, Y, and Z text boxes in the status bar.
- If the endpoint is the last point of the polyline object, double-click the point to complete the polyline or click Done on the shortcut menu.
- Click OK.
To delete the last point that was entered, click Undo Previous Segment on the shortcut menu. After using the undo feature, you can also use Redo Previous Segment on the shortcut menu.
To delete all points and start over, press Esc or click Escape Draw Mode on the shortcut menu.
If the Modeler option for editing properties of new primitives is checked, the Properties window appears, in which you can modify the object’s attributes.
Note: While drawing
a polyline, you can switch between arc line, straight line, or spline
segments using the Set Edge Type
options on the shortcut menu.
